Chirality, a pervasive phenomenon in nature, is widely studied across diverse fields including the origins of life, chemical catalysis, drug discovery, and physical optoelectronics. The investigations natural chiral materials have been constrained by their intrinsically weak effects. Recently, significant progress has made fabrication assembly low-dimensional micro nanoscale architectures, leading to discovery novel optoelectronic phenomena such as circularly polarized light emission, spin charge flip, advocating great potential for applications quantum information, computing, biosensing. Despite these advancements, fundamental mechanisms underlying generation, propagation, amplification chirality architectures remain largely unexplored. To tackle challenges, we focus on employing ultrafast spectroscopy investigate dynamics evolution, with aim attaining more profound understanding microscopic governing generation amplification. This review thus provides comprehensive overview micro-/nano-materials, two-dimensional transition metal dichalcogenides (TMDs), halide perovskites, metasurfaces, particular emphasis mechanism. further explores advancements research, thereby paving way innovative devices photonics

Abstract Chiral nanomaterials offer intriguing possibilities for novel electronic and chemical applications. Here, we report the discovery of an enantiomer-selective magnetoresistance effect in chiral gold nanocrystals. Based on precise control nanocrystal morphology using amino acid-directed synthesis, demonstrate that external magnetic field can dramatically modulate resistance enantiomer-specific manner. For a given enantiomer, one direction alters by over order magnitude, while opposite leaves it unchanged. This asymmetric response reverses enantiomer. We attribute this phenomenon to chirality-driven charge trapping mechanism, where interplay between selectively modifies surface potential. The magnitude sign be further tuned chemistry nanocrystal, as demonstrated through sulfide treatment. Our findings reveal new form chirality-dependent magnetoresistance, distinct from previously known effects such chirality-induced spin selectivity electric magnetochiral anisotropy. ability remotely potentials nanostructures fields could enable approaches catalysis, drug delivery, nanoelectronics.
